FAQ

What is the maximum operating frequency and CoreMark score of the R5F5671EDDLK#20?

The R5F5671EDDLK#20 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark performance. This score reflects deterministic execution of the RXv3 core's 113-instruction set, including double-precision floating-point and DSP extensions. The R5F5671EDDLK#20 sustains this performance across its full temperature range with zero-wait-state access to 384 KB SRAM and optimized flash cache hit behavior.

Does the R5F5671EDDLK#20 support secure boot and cryptographic operations?

Yes, the R5F5671EDDLK#20 integrates Trusted Secure IP (TSIP) with hardware-accelerated AES128/192/256, RSA, ECC, SHA256, and a true-random number generator. It supports secure boot verification, encrypted firmware storage, and key protection against illicit copying. These capabilities are certified for IEC60730 Class B compliance and are accessible via Renesas' Secure Boot Manager and TSIP driver libraries.

What package type and pin count does the R5F5671EDDLK#20 use?

The R5F5671EDDLK#20 uses the PLQP0144KA-B package: a 144-pin Low-Profile Quad Flat Package with 0.50-mm pitch, 20 × 20 mm body size, and exposed thermal pad. This package maps to the full RX671 Group pinout for 144-pin variants, supporting all peripherals including CAN, USB, SDHI, QSPIX, and CTSU. Pin compatibility is confirmed per Renesas document R01DS0373EJ0120.

Can the R5F5671EDDLK#20 execute code directly from external quad-SPI flash?

Yes, the R5F5671EDDLK#20 supports execute-in-place (XIP) from external serial flash via its QSPIX interface. The QSPIX module supports extended SPI, dual-SPI, and quad-SPI protocols with selectable address widths (8–32 bits), enabling direct instruction fetch without loading into internal RAM. This reduces boot time and extends effective memory capacity beyond on-chip flash limits.

How many A/D converter channels and what resolution does the R5F5671EDDLK#20 provide?

The R5F5671EDDLK#20 integrates two independent 12-bit S12AD units: Unit 0 with 8 input channels and Unit 1 with 12 input channels. Resolution is software-selectable at 8-, 10-, or 12-bit modes, with minimum conversion times of 0.42 µs (8-bit), 0.45 µs (10-bit), and 0.48 µs (12-bit). Both units include self-diagnostic functions and analog input disconnection detection.

Is the R5F5671EDDLK#20 qualified for industrial temperature range operation?

Yes, the R5F5671EDDLK#20 is rated for the industrial temperature range of –40°C to +85°C (D-version), as specified in Renesas documentation R01DS0373EJ0120. It undergoes full characterization across this range for all key parameters including CPU frequency, flash programming/erase endurance, ADC accuracy, and peripheral timing - with no derating required under nominal supply conditions (2.7–3.6 V).
